This text surveys major theorists in the psychology of religion--Sigmund Freud, C.G. Jung, William James, Erich Fromm, Gordon Allport, Abraham Maslow, and Viktor Frankl--who are all seminal thinkers and represent classical theories in this field. Each of these theorists presents a comprehensive theory of religion which attempts to give an account of the psychological origin and/or value of religion. The approach of the text, in each case, shows how the theory of religion emerges not only from the theorist's psychological theory but also from his own life experience.
